Human memory, cerebral hemispheres, and the limbic system: a new approach

An integrative approach to human memory is presented in the context of brain asymmetry. The results of psychophysiological investigations suggest that right-hemisphere functioning is closely associated with the limbic system; that association leads to the formation of a polysemantic context. Polysemantic context is determined by multiple interconnections among its elements; each element bears the stamp of the whole context. That context sustains episodic, personal, and emotionally laden memories. Left-hemisphere functioning leads to the formation of a monosemantic context, which is responsible for the maintenance of semantic memories. That distinction--in terms of general organization of material by hemispheres--explains such phenomena as memory disturbances among the very old, the influence of emotions on memory, and confabulations.     

The role of need level and/or need salience as moderators of the relationship between need satisfaction and work alienation-involvement

Contrary to previous findings documenting the importance of higher-order need satisfaction, a recent study by G. J. Gorn and R. N. Kanungo (Organizational Behavior and Human Performance, 1980, 26, 265–277) has indicated that satisfaction of lower-order needs may lead to job involvement if such needs are salient. Data from a heterogeneous sample of 632 employees from six organizations were used to test six hypotheses concerning the effects of need level (higher vs lower order) and need salience as moderators of the relationship between need satisfaction and alienation-involvement. Three different ways of operationalizing need saliency were used, including a replication of Gorn and Kanungo's procedure. Higherorder need satisfaction was correlated with alienation-involvement scores to a significantly greater degree than was lower-order need satisfaction, even for those for whom lower-order needs were most salient. Need saliency was not found to moderate the need satisfaction-involvement relationship when need level was controlled. Issues regarding the operationalization of “need salience” were discussed and a new measure of alienation-involvement (the A-I Scale) was introduced. Implications for further empirical investigations of the need saliency issue were noted, as was the universal application of job enrichment programs aimed at promoting higher-order need satisfaction.     

Motor performance under three levels of trait anxiety and stress

In general, the interactive effects of trait anxiety and stress on motor performance have been neglected in assessing the viability of the inverted-U hypothesis. The present investigation tested the inverted-U hypothesis using three levels of trait anxiety and psychological stress. Performance results produced an inverted-U curve for the three levels of stress, with subjects in the moderate-stress condition displaying the highest performance. In addition, a significant trait anxiety x stress interaction indicated that high trait-anxious subjects performed best in the low-stress condition, while low trait-anxious subjects performed best in the high-stressed condition. The discussion concerns theories attempting to explain the relationship between anxiety and motor performance.     

Reactions to pornography on a college campus: For or against?

In recent years pornography has become a controversial political/moral issue sparking intense debate among a variety of groups. The purpose of the research carried out in 1988 and reported here was to examine attitudes about and exposure to sexually explicit materials for a representative sample of predominantly Caucasian students at a state university in the Midwest. Results indicated that a majority defined pornography as media portraying explicit sexual activities, agreed that adults should have access to sexually explicit materials, and attributed both harmful and positive effects to such materials. Respondents tended to endorse either the views that sexually explicit materials are harmful, do not have positive effects, and should be restricted, or the opposite views that they are not harmful, do have positive effects, and should not be restricted. Women, more religious respondents, less sexually active respondents, and those who had never seen such materials endorsed the more negative evaluations. These students' views are compared with those of a representative sample of the county as a whole, as well as with residents of other locales in the United States. Results are also discussed with respect to four conceptually distinct positions on the pornography issue.We wish to thank Leslie Morgan and Brian Powell for their helpful comments on a draft of this paper.     

The impossible reparation

This article discusses the phantasy of returning to the past and symbiotically merging with the mother, which, in an autistic patient, constituted an attempt of impossible reparation. This mode of reparation resulted in a cycle in which any attempt to repair the inner experience by contact with an external object was destined to be disappointing because of the desire for an infantile connection without separateness. The author reviews the literature on reparation and emphasises recent developments resulting from work with Autism Spectrum Disorder children who are far from the depressive position and who have difficulty bearing separateness. The author recognises an essential positive aspect of reparation independent of the ability to perceive the object as separate and suggests that when working with very primitive emotional states, it seems suitable to use a wider definition for what can be considered essentially a primitive reparative act or a precursor for reparation. Next, the author discusses the significance of a phantasy of impossible reparation in an autistic girl with emphasis on the importance of considering the reparative aspects of this defensive phantasy to enable development. Finally, the author relates to the despair that occurs in both analyst and patient when the phantasy is not transformed.     

Field validity of heart rate variability metrics produced by QRSTool and CMetX

Interest in heart rate variability (HRV) metrics as markers of physiological and psychological health continues to grow beyond those with psychophysiological expertise, increasing the importance of developing suitable tools for researchers new to the field. Allen, Chambers, and Towers (2007) developed QRSTool and CMetX software as simple, user-friendly tools that can be used to compute metrics of HRV. In the present study, the authors examined the field validity of these software tools-that is, their validity when used by nonexperts. In a lab with extensive expertise in psychopathology but not psychophysiology, ECG data were obtained from 63 undergraduates at baseline and during a stressor and then processed using QRSTool and CMetX to produce the 10 HRV indices described in Allen et al. (2007). The indices displayed factor structures and patterns of changes from baseline to stressor that were similar to findings from Allen et al. and consistent with how indices of parasympathetic and sympathetic activity should behave. Results support the field validity of QRSTool and CMetX, suggesting that they are useful for nonexperts in psychophysiology interested in measuring HRV.
